Architect: Mats Wedberg, Hallstavik, Sweden
Completion: 1993
Area: 140 m^2The two-storey building belongs to the
building complex of a Waldorf school. It
contains two classrooms, each with a small
entrance hall.
The basement walls are built of two layers
of 15-cm-wide lightweight concrete blocks
and 20 cm intervals, the cavities being filled
with perlite for thermal insulation. The first
floor has 50-cm-wide load-bearing walls
of solid loam loafs, topped by a timber ring
beam. The loafs were formed by hand from
local clayey soil following the rules of the
Dünne loam loaf technique, described in
chapter 8.
The roof is carried by a timber frame struc-
ture, isolated by turf and covered by stone
slate shingles.
The rooms are heated by open fireplaces.
